Abstract: The project explains the work done to achieve required active and reactive power in the output of converter with maximum wind power extracted through matrix converter with space vector modulation (SVM) fed grid combined Voltage Oriented Vector Control scheme (VOC). Direct matrix converter is applied and PMSG based Wind Energy Conversion System (WECS) is used for the proposed work. The reference for active power is the maximum extractable power which is calculated while reactive power reference is considered as zero. The change in wind speed changes generated power which is regulated using PI controller and it regulates the voltage ratio of the Matrix Converter (MC). This VOC scheme evaluates WECS maximum power and it is fed to the grid at the required output voltage and frequency, also at approximately unity input power factor. Under variable wind speed, the generated power voltage and frequency fluctuates in grid side and also load side. Even changes in speed of wind mill, the proposed system regulates the output power at evaluated maximum power of wind.
